Proof of Concept
The media below is both a demonstration of artistic technique and the implementation of the installation concept. The first video documents physical interaction with the screen using my pure data patch. The second records an experiment with steam shot at a high frame rate and using a macro lens. The pictures are a preliminary mock up of the installation made using Cinema 4D. An early illustration of the installation can be found below as well.

Next Steps
Going forward, I will continue to conduct experiments using a fog machine, oscillating ultrasonic humidifier, and a vacuum. Concurrently, I'm doing a bit of research on cloud chambers as well. [1]. As an aside, Dutch artist Berndnaut Smilde recently generated artificial nimbus clouds in an exhibition space by regulating the temperature and humidity of the space.[2] My ultimate goal is to be able to control the density and movement of the fog based on the movement of the viewer in the installation space.
